          kexec is a system call that implements the ability to shutdown your
          current kernel, and to start another kernel.  It is like a reboot
          but it is independent of the system firmware.  And like a reboot
          you can start any kernel with it, not just Linux.

          The name comes from the similarity to the exec system call.

          It is an ongoing process to be certain the hardware in a machine
          is properly shutdown, so do not be surprised if this code does not
          initially work for you.  It may help to enable device hotplugging

          you have a system with more than one CPU, say Y.

          If you say N here, the kernel will run on single and multiprocessor
          machines, but will use only one CPU of a multiprocessor machine. If
          you say Y here, the kernel will run on many, but not all,
          singleprocessor machines. On a singleprocessor machine, the kernel
          will run faster if you say N here.

          People using multiprocessor machines who say Y here should also say
          Y to "Enhanced Real Time Clock Support", below.

          Find out whether you have ISA slots on your motherboard.  ISA is the
          name of a bus system, i.e. the way the CPU talks to the other stuff
          inside your box.  Other bus systems are PCI, EISA, MicroChannel
          (MCA) or VESA.  ISA is an older system, now being displaced by PCI;
          newer boards don't support it.  If you have ISA, say Y, otherwise N.

config EISA
        bool
        ---help---
          The Extended Industry Standard Architecture (EISA) bus was
          developed as an open alternative to the IBM MicroChannel bus.

          The EISA bus provided some of the features of the IBM MicroChannel
          bus while maintaining backward compatibility with cards made for
          the older ISA bus.  The EISA bus saw limited use between 1988 and
          1995 when it was made obsolete by the PCI bus.

          Say Y here if you are building a kernel for an EISA-based machine.

          Otherwise, say N.

config MCA
        bool
        help
          MicroChannel Architecture is found in some IBM PS/2 machines and
          laptops.  It is a bus system similar to PCI or ISA. See
          <file:Documentation/mca.txt> (and especially the web page given
          there) before attempting to build an MCA bus kernel.

         The Maple Bus is SEGA's serial communication bus for peripherals
         on the Dreamcast. Without this bus support you won't be able to
         get your Dreamcast keyboard etc to work, so most users
         probably want to say 'Y' here, unless you are only using the
         Dreamcast with a serial line terminal or a remote network
         connection.

          Compact Flash is a small, removable mass storage device introduced
          in 1994 originally as a PCMCIA device.  If you say `Y' here, you
          compile in support for Compact Flash devices directly connected to
          a SuperH processor.  A Compact Flash FAQ is available at
          <http://www.compactflash.org/faqs/faq.htm>.

          If your board has "Directly Connected" CompactFlash at area 5 or 6,
          you may want to enable this option.  Then, you can use CF as
          primary IDE drive (only tested for SanDisk).

          If in doubt, select 'N'.

          If your board has "Directly Connected" CompactFlash, You should
          select the area where your CF is connected to.

          - "Area5" if CompactFlash is connected to Area 5 (0x14000000)
          - "Area6" if it is connected to Area 6 (0x18000000)

          "Area6" will work for most boards.
